THILL=CUPLING.

SPECIFICATION forming part of Letters Patent No. 369,689, datedSeptember 13, 1887.

Application filed December 27, 1886. Serial No. 222,729. (No model.)

To all whom it 71mg/ concern:

Be it known that I, STEPHEN BURDsALL, of Fremont, in the county ofSandusky and State of Ohio, have invented certain new and usefulImprovements in Thill-Oouplings, of which the following is aspecification.

This invention relates to thill-couplers, and has for its object toprovide against the rattling of loose parts; and it consists in thepeculiar construction and combination of the several parts comprising mydevice, as hereinafter fully described, and pointed out in the claim.

I-n the accompanying drawings, Figure 1 is a perspective view of my newthillcoupler. Fig. 2 is a detached view of the clip baseplate having theeye-arms forming a part thereof. Fig. 3 is a detached view of thecoupling-bolt, showing a slot by which it is secured in place in thesaid eye-arms. Fig. 4 is a detached view of a metal spring-plate. Fig. 5is a detached view of a hooked latching device located inrear of thecouplingbolt and designed to lock the coupling-bolt and bearing againstthe spring. Fig. 6 shows a clip with arms attached forming part thereof.

A is a base-plate secured to the axle by a clip, B, and has two arms, OO, formed with it, having eyes o c. The rear ends of said arms formshoulders which bear against the side of the axle, and the rear end ofthe plate also has a shoulder bearing against the rear side ofthe axle,and tlie plate has two holes for securing it to the axle by means of aclip, B.

D is a thilliron of the common construction, and E is a coupling-bolthaving a crosscut slot or groove near its point, instead of beingscrew-threaded, for a purpose hereinafter shown.

G is a pin or bolt having leaf H on its middle part, and also having onone end a latchhook, K, which engages with the slot or groove in thecoupling-bolt E. In the rear part of the arms O O are made holes I I,for the reception of the pin G, one of said holes having a slot, t', inconnection with it to let the leaf H pass through in inserting the saidpin.

L is a metal leafspring, foldednto be placed between thethilliron andthe pin or bolt G, as seen in Fig. 1. The forward end is bent intohalf-circle to lit around the end of the thill-iron. A block ofindia-rubber may be substituted for the metal spring with the sameeffect.

In Fig. 6 the arms O O are formed on the clip. The'effect is with.regard to firmness.

From the foregoing it will be seen that the spring, bearing against boththe thill-iron and leaf on the pin, will effectually prevent anyrattling of the parts, and also that the position of the leaf on the pinis such that it, by the tension of the spring, holds the latch downfirmly upon the coupling-pin, thereby locking the parts together. Bythis construction, also, it will be seen that the coupling or theuncoupling of the thills is very quickly and readily done.

Having described my invention, what I claim, and desire to secure byLetters Patent,

The combination, with a clip-iron having the eye-arms and a thill-iron,of a couplingbolt having a cross slot or groove near its point, a pin orbolt in rear ot' the coupling bolt and having a leaf, and a hook-arm onoutside of eye-arm' and engaging with said coupling-bolt, and aspring-bearing between the thill-iron and the said leaf on rear bolt,all constructed to operate substantiallyinthe manner and for the purposespecied.

STEPHEN BURDSALL.
